Server React DOM APIs

The react-dom/server APIs let you server-side render React components to HTML. These APIs are only used on the server at the top level of your app to generate the initial HTML. A framework may call them for you. Most of your components don’t need to import or use them.

Server APIs for Web Streams

These methods are only available in the environments with Web Streams, which includes browsers, Deno, and some modern edge runtimes:

• renderToReadableStream renders a React tree to a Readable Web Stream.
• resume resumes prerender to a Readable Web Stream.

Node.js also includes these methods for compatibility, but they are not recommended due to worse performance. Use the dedicated Node.js APIs instead.

Server APIs for Node.js Streams

These methods are only available in the environments with Node.js Streams:

• renderToPipeableStream renders a React tree to a pipeable Node.js Stream.
• resumeToPipeableStream resumes prerenderToNodeStream to a pipeable Node.js Stream.

Legacy Server APIs for non-streaming environments

These methods can be used in the environments that don’t support streams:

• renderToString renders a React tree to a string.
• renderToStaticMarkup renders a non-interactive React tree to a string.

They have limited functionality compared to the streaming APIs.
